The test is a bit limited because it’s based on sine waves rather than real music, but it’s a start. I had a theory that Opus -> Opus would have less conversion loss than AC3 -> Opus, but never tried to prove it until now. I did another round of tests to measure distortion due to double format conversion. Here is a Dropbox link for the test problem: I am always using aac audio codec and, for rate control, I’ve tried average, constant, and quality-based VBR. I tried the default YouTube settings, activating and de-activating both parallel processing and hardware encoder. The audio peak meter is always below -6, mostly below -10. The original file is clean (no noise) and the playback on editing mode is also normal except from lag-generated noises. I am running the latest version of Shotcut and already tried re-installing it.

mp4 video and the problem still persists. I usually have 2-3 video tracks (.mp4/60FPS) and a single audio track (.wav), but I made a simple test problem with a single audio file (.wav or.

I have gone through many other similar posts, but could not find a solution. I am having problems with crackling, popping, distorted, crunched paper kind of sounds in my exported videos.
